This invention relates to irrigating devices through a suitable train of reducing gears particularly of the type known as overhead here indicated by pinion +1, gean5, pingvvhe'el irrigating systems, and has for its main -ob- 6 ear 7 pin wl'icel 8, gear 9,. pinions lfland ject and feature the production of simple and 11 the latter ll, being mounted on shaft 12 inexpensive means for oscillating a sprinkler carrying gear 2. p I k V r pipe, such means being at the same time not The problem is to oscillate the sprinkler 60 only flexible so that adjustments can be readpipe 1 from gear'Q and todo this in a positive, ily made to vary the character of the oscillasimple and. adjustable manner. To this end tion and the amplitude of the stroke of oscilsuitable driving. connections are utilized inlation but also positive in their action so that cludinga variable-speed cam-gear or a vatheoscillationmayftake place uninterruptedly riahlespeed member 14 and thiscam gearis 65 and at such varying speed that thefdistribuhere shown connected to an arm 15 attached tion of water over a given surface is substanto the. sprinkler pipe.

These two holes and the outermost hole 10 are arranged, with respect to each other, in an arc of a circle the center of which is the center of oscillation of the sprinkler pipe as indicated in Fig. 3, and it will be understood that, When bolt 16 is placed in hole 21 (Fig. 5), the oscillation Will be entirely at the left hand side of the vertical, and that, When bolt 16 is placed in hole 20 (Fig. 6) the oscillation will be entirely at the right hand side of the vertical. Of course, there may be a series of holes 20 and another series of holes '21 as shown to thereby vary the amplitude of the stroke at either side or the vertical.
